The 15 Y/O Turbo M42 Build Thread (Now Holley EFI Terminator X Controlled)

[Jaker]

I might have missed it. How much boost are you running? That 2.5bar sensor is good for 22-23lbs of boost.

I like the hard work you put in to it!:up:

[Dj Buttchug]

Installed 3 Bar GM map Sensor. Previous settings were at 2.5 Bar which isn't enough. This means the whole tune is off btw. So now I have to re adjust everything.

[Dj Buttchug]

lots of work to be done

[whodwho]

They don't seem to supply brackets, bmwandhonda had to build brackets for his touring ITB build as well

Yeah nah that's not normal, is a good reason why OEM is bolted down.
That honestly surprises me, I thought Nuke were a good brand

[Dj Buttchug]

It drops in but there is no way to secure the rail to the intake so its just free ballin. Is this how they normally install fuel rails? I feel like a good about of boost will pop the injectors and the rail right out of the intake runners if you don't have it bolted down somehow

[econti]

They don't drop in? That's a pisser. Was thinking of getting one myself

[Dj Buttchug]

Note that Nuke Performance make a rail for them that is supposedly drop in

This is true and I have one. The only issue to resolve is mounting it properly. I am working on some custom brackets to make it work.

Nice build, now that I'm in San Diego will have to check this car out when I have time

[Dj Buttchug]

As my refinements continue I am focusing on a couple areas and one is my fuel system. The OEM M42 fuel rail is nice because it fits properly and uses the factory mounting points. On the flip side, I have no idea what is going on with my fuel pressure and I'm probably using a 20 year old regulator. The engine runs well but I'm skeptical my regulator might be doing stupid things under boost. (weird fluctuations in AFRs amongst other things)

so

Last week I made a decent purchase and by decent I mean these little shits are expensive. FuelLab is a pretty cool company and after some researching they have some really nice products that are sized properly for what I was looking to accomplish.

The pressure gauge is low budget but it should work fine for now. I used a factory mounting point in the engine bay to hang the adjustable regulator. Here it is all setup nice and clean.



Happy with the end result I am now waiting for all of my AN fittings to arrive so I can build the rest.

Dang looks nice.

[Dj Buttchug]

Very nice dude, super clean as usual too. GET THAT THING ON A DYNO ASAP! Also how's the car sound with the new manifold's?

Shooting for dyno in the next week or two! It sounds about the same. Its fairly quite for what it is. I expected it to be much louder.

What size rims and tyres are on the black car? Can you go foot to floor in 2nd or 3rd gear and get traction?

15x7 205/50 and no not really. Im not sure what to do about this issue yet...
